lllLAGHINE FOR "WASHING RUBBER All Application filed November 12, 1923.

To all whom it may concern Be it known that l. FRITZ Knirrrnn, a citizenor" Germany, residing at Stuttgart, Germany. have invei'lted certain newand useful ilimprovements in ll lachines for VVa-shing Rubber and thelike, of which the following is a specification.

My invention refers to improvements in devices for washing rubber andthe like in which rotary squeezing rolls are disposed in a washingtrough, the bot-tom of which is slotted after the manner of a sieve,removable closing ledges being introduced into these slots.

In machines of this kind, these removable ledges are not easilyaccessible. In order to replace them, it is necessary to insert the hand into the channel below the trough, and the removal of the ledges isparticularly diflimit in the case where foreign bodies or small piecesof rubber have been caught between the bottom and the ledges. Moreover,each ledge forms an obstacle with regard to the other ledges whichextend across the entire width of the trough and are comparatively thin,whereby they are liable to get easily bent.

In the machine according to the present invention, these drawbacks areavoided by arranging the slotted bottom together with the closing ledgesin an inclined. plane. I am thus enabled to provide a. lateral openingwhich can be closed by a cover and through which each ledge can easilybe removed. ltcloreover, the different parts serving to sepmate theforeign matter from the rubber can now be arranged on one side near thelowest point of the bottom, the machine being thus rendered far simplerand smaller.

In the drawings affixed to this specification and forming part thereof,a device embodying my invention is illustrated diagrammatically invertical section.

Referring to the drawing, a is the machine bed and Z2 is the washingtrough tiltably mounted on the bed. 7 and g are the squeezing rollsarranged in the trough for rotation in the direction of the arrows. Thebottom of the trough is shaped in accordance with the rolls and in themiddle between the rolls the well known saddle piece 2" is arranged.

Serial No. 674,409

Several slots 8 extending across the whole width ot the trough arerovided. in the bot tom and closing ledges 4: are arranged to beintroduced into these slots from below, their ends being then insertedin suitable notches provided in the end taces of the trough.

The bottom is inclined as shown in the drawing and, consequently, theslots 8, as well as the closing ledges 4 are disposed on differentlevels. This applies also to the rolls 7 and g.

The slots and closing ledges can easily be inspected and the ledgesremoved through the channel 9 which can be closed by means of a hingedcover 10.

The protective edge is and the perforate wall on, the settling chamber11 and the overflow o are disposed on the opposite side. Thisarrangement provides for a higher and therefore larger sieve surface. Onthe other hand, such specifically heavy impurities as are carried by theupper roll 9, are vigorously crowded together under the action of thewater current in. the direction towards the protective edge which formsthe lowest point of the washing trough proper, whereby they are quicklyremoved out of reach of the rolls.

I wish it to be understood that I do not desire to be limited to theexact details of con struction shown and described, for obviousmodifications will occur to a person skilled in the art.

I claim:-

1. Device for washing rubber and the like, comprising in combination, amachine bed, a washing trough tiltably mounted on said bed, a pair ofsqueezing rolls mounted in said trough in parallel with each other, aninclined slotted bottom underneath said rolls, closing ledges removablydisposed in the slots of said bottom and a lateral opening in saidtrough through which these ledges can easily be removed.

2. Device for washing rubber and the like, comprising in combination, amachine bed, a washing trough tilta'bly mounted on said bed, a pair ofsqueezing rolls mounted in said trough at different levels in parallelwith each other, an inclined slotted bottom underneath said rolls,closing ledges removably disposed in the slots of said bottom andunderneath said rolls, closing ledges removably disposed in the slots ofsaid bottom, a lateral opening in said trough through which these ledgescan easil be removed a sieve and a protective edge, being disposed onone side oi said trough near the lower roll.

In testimony whereof I allix I11 7 signature.
